T on whom it may concern.-

Be it known that I, JAMES M. SWEENY, a

citizen of-the United States, residing at Aspinwall, in the county ofAllegheny and State of Pennsylvania, have invented or discovered certainnew and useful Improvements in Ma-- chines for Making Carbon-Black, ofwhich improvement the followin is a specification.

The invention descri ed herein relates to certain improvements in theapparatus of the manufacture of carbon-black. It has. heretofore beencustomary in the manufacture of this material to arrange the as-burnersin such relation to the surface 0% the plate on which the black isdeposited that the flames will impinge at right an les to such surface,and in order to prevent t e products of combustion from extinguishin theflame it has been necessary to arrange t e burners at some distance fromthe receiving-surface, thereb giving an op ortunity for'the access ofsuc uantities 0 oxygen and under such conditions as to permit of a hotflame, with the consequent result of burning a portion of the carbonbefore impact against the surface and lso of a portlon of the blackalready deposited;

It is the object of the present invention to so arrange the burner anddeposit receiving surface in such relation to eac other that the flamewill impinge against. the surface at an angle less than a right angleand -the flame Wil have a longer contact with such surface. By reason ofthis angular impact of the flame the point of impact will be at one sideof the burner, and hence the products of combustion produced will not bethrown back directly against and "around the flame, thus avoidingextinguishing the flame and .permitting a closer arrangement of theburner to the deposit-receiving surface.

The invention is hereinafter more fully described and claimed. a I

In the accompanying drawings, forming a part of this speclfication,Figure 1 is a vertical section of my improved form.of construction 'ofapparatus. Fig. 2 is a horizontal section view, the lane of sectionbeing indicated by the line I II, Fig. 1. Fig. 3 is a similar view toFig. 1, showing a modification of the apparatus. Fig. 4 is a horizontalsection view on a plane indicated by the line IV IV, Fig. 3; and Fig. 5is a detailed view, on an enlarged scale, of a form of burner.

In the form of apparatus shown in Figs. 1 and 2 the deposit-receivingsurface 1 is sup position by means ported at its periphery upon suitableposts or standards 2, said posts or standards being connected bycross-bars 3, to which is secured the upper bearing 4 of the hollowshaft 5. This shaft extends down through a stuffingboxfi onto a suitablebearing formed in the bearing-block 7, through which is formed a passagecommunicating with the hollow shaft 5. This passage is connected to asuitable source of gas or oil supply, and on the shaft is secured apulley 8, whereby the shaft may be rotated as required. Radial arms 9are eecured to the shaft in suitable relation to the plate 1, and to theouter ends of these arms 9 is secured an annular ring 10, provided witha series of burners 11.

at an angle less than a. right an 1e and, preferably, quite acuteagainst the pate 2. It is preferred that the shaft and burners should berotated in such direction as to exert a pull These burners are soconstructed or arranged as to direct the flame on the flame away fromthe burner, thereby causing a considerable extension of the flame. Inorder to collect the carbon-black deposited on the plate, from .which itis removed by scrapers 12, supported on an arm 13, carried by the shaft,a basin 14 issecured to the standards below the plate 1, the walls ofsuch basin inclining toward an outlet- .spout 15. In order to insure theremoval of the carbon-black from the basin, brushes or scrapers 16 aresecured to the shaft so as to sweep around the inner surface of thebasin and push the material into the spout. The lower end of the spoutis connected to suitable means for conveying the lampbl'ack awaysuch,for example, as a passage 17,in which is arranged a screw 18, adapted topushthe material'alongithe passage to the discharge-o enin 19.

y In lieu o. revo ving the burners, as .in the construction shown inFigs. 1 and 2, the plate 1 may be secured to a vertical shaft 5, havingits lower end mounted in asuitable step 20, the shaft being supported ina vertical of braces 21, preferably provided with antifTiction-rollers22, b string against the shaft' The burners 11, which are arranged inthe same relation to the plate 1' as in the construction shown in Figs.1 and 2, are secured to an annular pipe 23, connected by a pipe 2 1300 asuitable source of gas or oil supply. The arm 13", carrying the scrapers12, is secured to one of the posts or side walls so shaped as to directthe car onstandards 2, and a hopper 14 havin its a fan-like flame or togive a narrower flame,

as required by conditions of work. .As stated in regard to theconstruction shown in Figs. 1 and 2, the point of impact of the flame ismoved away from the burners, so that the flame will be eXtcndedand dragalong the plate, or the plate will be moved along the flame, thusremoving the smoke-deflecting point away from the flame and preventinany smothering or extinguishing thereof an also preventing thecombustion of the deposited carbon by the 'fiame. The point at which thesmoke and unconsumed gases im pinge upon the plate is carried away fromthe burners, and as such impingement is at an angle the smoke andunconsumed gases I will be deflected away from thetburner, and

the latter can bearranged in verymlose proximity to the carbon-receivingsurfaces/thus preventing the access of such quantities or..

produce a hot carbonranged to direct the ame against the plate at anangle less thania right angle, and in a direction that a pull is exertedonthe flame by the relative movement. .of said parts whereby thereflected'gaseous products 'of combustion are drawn away from'the pointsof combustion. j
